Lette/rs Patent No. 90,532, dated May 25, 1869.

The Schedule referred to in these Letters Patent and `making part of the same.

-ama# To all whom 'it may concern;

Be it known that we, JOHN HAMILTON, L. E. HAN- soN, GEORGE W. HAMILTON, and"JosEPH HAMIL- TON, of Wheeling, in the county'of Ohio, and in the State of Test Virginia, have invented certain new and useful Improvements in Ore-Crusbers; and we ,do hereby declare that the following is a-full-,clean and exact descriptionthereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which- Figure 1 is a perspective view,

Figure 2 is a side view, and

Figure 3 is-a plan view of the bottom, or hopper.

Figure 4 is a plan view;

Figure 5 is a cross-section through the hopper, or bottom, at a; x of iig. 2; and

Figure is a side view of one of the braces attached to the brace and axle.

The nature of our invention consists, in the manner hereinafter described, in making and operating a coinbined ore-crusher.

To enable others skilled in the art to make and use our invention, we will describe its constructionand operation, so that any one skilled in the art can construct and operate the same.

In the construction of our invention, in iig. 1, A is the bottom, made of solid plank.

B B B B, four standards, rising up higher than the crushing-wheels.

Diagonally to these uprights are cross-bars O O, crossing each other in the centre at iight angles, and

which constitute the frame-work of the machine.

D is au upright shaft, resting on the bottom, having va journal, E, attached to the bottom by means ot' A straight shaft, G, passes at right angles to the' upright shaft, and through it, and which is the axle on which the wheels revolve.

` On this cross-shaft or axle are placed, between the wheels and upright shaft, two sleeves, H H, which serve to keep the wheels in proper position in revolving, and to prevent them from ruiming lin toward the centre.

Directly above this axle is an arm, T, upon the upright shaft, at right angles to the axle, and is to support `the braces K K, which extend out beyond the wheels, and 4to which are attached rods L L, which are attached to the axle at each outer end, and are to hold the wheels on the axle.

On the upper cud of this shaft D is a wheel, M, to which the power is applied to operate the machine.

The wheels N N are made very heavy, and may be cast solid or in two pieces, made plain or .convex on their sides.

To these wheels are attached chilled-iron rims, made as hard as it is possible'to do so by the art of chilling.

These rims are cast in sections 1,*2, 3, 4, and on the inside of each section are two dovetails, extending across the iunerfface 'of the rim, which are fitted into corresponding grooves ou the periphery of the Wheels.

The whole having been fitted snugly, are,-when put on,`perfectly tight, and form a. solid Wheel.

A journal-box, a', is let into the Wheels, through which the axle passes, 4which also can be removed when worn'out.

The bottom, or hopper B, (like-letter in each gure designating the like parts of the machine,) is made dish-shaped, flaring out at the top, and may be varied in depth as required.

In-the centre, where, the journal on which the upright shaft rests, it is'raised some distance above the bottom, where the ore is crushed..

The crushing-Hoor is made in sections 5, 6, 7, 8, of f hard-chilled iron, andlissnugly fitted into position, and is then screwed down on the frame or bottom,

These hard-chilled sections, if they should break'or wear out, can be easily replacei by others.

In the bottom is a spout, b, where the crushed ore is let out, and passes away from the machine.

ln the operation of our invention, having constructed it as described, the ore is` placed in the hopper or bottom, and power is applied to the drivingwheel, which causesthe wheels to revolve, and by-the l great weight of the same ,the ore is soonl crushed, 'and .passes out through the spoutb, andl thus continue the operation of crushing as long as desired, or .when desired. d i

One of the great advantages in construction is in the axle being straight. lt is simply pushed through the wheels, sleeves, shaft, and support-braces, without any lifting, and is at any time as easily detached.

Having thus described our invention, we do not claim the wheels, shaft, or basin separately or in combination, for these we know to be old; but

The arrangement hereindescribed of the .arms I, secured to the upright shaft, the braces KK, extending out beyond the wheels, the rods L L on the axle G, andthe detachable sleeves H H, for keeping the wheels in place, all constructed and operated in the manner set forth.

In testimony that we claim the above-described certain new and useful improvements in ore-crushers, we have hereunto signed our names, this 8th day of December, 1868.

JOHN HAMILTON. L. E. vHANSON. GEO.,W. HAMILTON. JOSEPH HAMILTON.
